System: Ubuntu 16.04.5 LTS - Unity Desktop fresh install Dell XPS 9650 Intel 7700 HQ + Nvidia 1050 GTX mobile
I'm trying to get Nvidia drivers (415) + Cuda + prime select to run on my work Notebook. But every time the Intel graphicscard is selected, all symlinks are destroyed:

I've read:
How to get nvidia-persistenced daemon to work properly?
https://bugs.launchpad.net/ubuntu/+source/nvidia-persistenced/+bug/1693123
But there only seems to be to two valid solutions:
- Don't use Unity + GDM -> which I can't do, since we still deliver Software for 16.04 LTS, which needs to be tested in Unity
- Use Nouveau or Intel drivers -> which isn't what i want to do since I want to use CUDA
So unless anyone knows something better I would create an alias which calls a wrapper script recreating all symlinks after switching.
Also does anybody know what the root cause of this problem is. Why are the symlinks delted?
